Unskilled and unaware of it

Unskilled and unaware of it: How difficulties in recognizing one’s own incompetence lead to inflated self-assessments.

Kruger, Justin; Dunning, David

Journal of Personality and Social Psychology. Vol 77(6), Dec 1999, 1121-1134. doi: 10.1037/0022-3514.77.6.1121

Je comprends un peu mieux, ça ou ça, d’où le post d’un article qui date un peu.

Casey Luskin

Si vous ne souffrez pas de coulrophobie (vérifiez là, au cas où), que vous voulez vous marrer autant qu’en lisant The Book de Jean Staune, la dernière de Casey Luskin fera l’affaire.

Le mec est en train de découvrir les promoteurs et autres éléments qui régulent la transcription. Il était temps.
Et il fait sa découverte non pas dans un bouquin pour débutants (comme il aurait dû) mais à partir des dernières découvertes scientifiques, pas moins. Dire qu’il y en a qui ont eu un prix Nobel pour ça et que ce pauvre Luskin n’attirera que les rires de la foule. Certes, il a plus de 43 ans de retard sur les attributions des prix Nobel, mais un si grand IDiot pourra rattraper ça en un rien de temps.

Il conclue sa prose à la con par :

Most studies that have claimed that humans and apes have nearly identical genomes have primarily looked at the gene-coding portions of the genome, not the non-coding DNA (formerly claimed to be “junk”).

Ignorant les études par hybridation génome à génome aussi, ou les plus récentes comparaisons directes des séquences des génomes.

Je n’arriverai probablement jamais à comprendre comment des gens aussi ignares peuvent avoir autant de certitudes. Mais je comprends très bien comment leur ignorance les pousse à sortir autant de conneries.

Bah, de la rigolade à bas prix.

Ils supportent Obama et ils ont un prix Nobel.

Et, bien sûr, ils jouent à « j’ai la plus grosse » liste de scientifiques qui me supportent😉

that’s what puzzles are made for!

Tom Roud’s recent post of the puzzle from « The Last Theorem » and the fun I had with it, combined with this post on ScienceDaily remind me of the fun I had with Steve Jurvetson’s puzzles, one of them dealing with the millimeter wave Holographic Body Scanner which he had experienced.

A lot of fun, with nice people. And that’s part of the Web. I miss that. And Steve, Gisela, Bill, Bala and the others.

Nuts, all over the Web (and in-RL). Interesting people, rather sparse and rare.

Trying to fight against idiots don’t get you to help them recover from their condition. Just doing what’s necessary to make clear they are idiots is enough, but is it necessary?

Then spending more time with interesting people!

I’ll have to reconsider and make a decision. I’ll take the next three days off. Don’t mess with the Web😉

In Vitro Differentiation of Mouse Embryonic Stem Cells Into Primitive Blood Vessels

In Vitro Differentiation of Mouse Embryonic Stem Cells Into Primitive Blood Vessels

Svetlana N. Rylova, Paramjeet K. Randhawa, and Victoria L. Bautch

Methods in Enzymology, Volume 443 DOI: 10.1016/S0076-6879(08)02006-5

Mouse embryonic stem (ES) cells, derived from the inner cell mass of blastocyst stage embryos, undergo programmed differentiation in vitro to form a primitive vasculature. This programmed differentiation proceeds through similar processes of vasculogenesis and angiogenesis found during early vascular development in vivo. Partially differentiated ES cell clumps or embryoid bodies (EBs) first form blood islands that are subsequently transformed into a network of primitive blood vessels that contain lumens. Therefore, vascular differentiation of ES cells is an ideal model to study and manipulate early vascular development. Here we provide protocols for the routine maintenance of mouse ES cells and in vitro differentiation. We also include protocols for establishing transgenic ES cell lines and visualization of blood vessels by use of endothelial specific molecular markers.

Strictly scientific, well maybe not, let’s see…


The Pontifical Council for Culture, Rome’s Pontifical Gregorian University and the University of Notre Dame in Indiana are organizing an international conference in Rome March 3-7 as one of a series of events marking the 150th anniversary of the publication of Charles Darwin’s « The Origin of Species. »

Jesuit Father Marc Leclerc, a philosophy professor at the Gregorian, told Catholic News Service Sept. 16 that organizers « wanted to create a conference that was strictly scientific » and that discussed rational philosophy and theology along with the latest scientific discoveries.

He said arguments « that cannot be critically defined as being science, or philosophy or theology did not seem feasible to include in a dialogue at this level and, therefore, for this reason we did not think to invite » supporters of creationism and intelligent design.
